About Dioxycle
Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency. DIOXYCLE first targets ethylene, the world’s most consumed organic chemical, widely used for the production of textile fibers, plastics, construction materials and furniture. With its unprecedented approach, Dioxycle scales the first sustainable technology with the potential to reach cost parity with fossil incentivizing fast adoption and decarbonization. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing over 2% of the world's emissions.
Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality by developing a completely novel technological approach. Having completed our medium-scale Proof-of-Concept electrolyzer, we are now working towards a first-of-its-kind large-scale industrial prototype and are assembling key partnerships for future commercial roll-out.
We are supported by world-class funders including Lowercarbon Capital, Breakthrough Energy Ventures and Gigascale Capital and have raised $26M to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)
Your Mission
Dioxycle is seeking a highly talented and driven Process engineer to join our team at this pivotal phase of transition from R&D to industrial piloting. Partnering with our existing process team, you will contribute through the definition and review of various processes to the development of our first-of-its-kind technology and our first industrial pilot. As such, your responsibilities will center around:
Process engineering
- Define PFDs (Process Flow Diagrams) and P&IDs (Piping and Instrumentation Diagrams) both from documented processes and leveraging your experience
- Develop process simulation files using specialized software for the planned process chain
- Draft requirement specification documents directed towards technology providers and/or engineering companies
- Benchmark current available process technologies that meet requirement specifications
- Engage with technology providers and establish collaborative partnerships
- Conduct experimental internal tests or collaborate with partners to evaluate third-party process technologies performance
- Introduce innovative strategies to continuously enhance process integration and increase energy efficiency
- Refine both energy efficiency and financial aspects (OPEX and CAPEX) of individual units and/or the entire process chain
Pilot development
- Contribute to the conceptualization, design, and development of our industrial carbon electrolyzer plant
- Collaborate with an engineering company from the feasibility, through concept development and FEED phase to detailed engineering stages.
- Participate in P&ID concept review, HAZOP study
- Oversee Factory Acceptance Testing (FAT) activities
- Contribute to pilot commissioning phase and iterative improvement
